Japanese Patent Laid-Open No. 2001-022354
A performance means having an arpeggio generation function that generates an arpeggio (distributed chord) in response to an operation of a predetermined performance operator (for example, a key pressing operation on a keyboard or the like) by a user is commonly referred to as an “arpeggiator”. A conventionally known arpeggiator stores, as an arpeggio pattern, at least a plurality of key numbers (not note numbers (pitch information) corresponding to pitches, but simple numbers) and sounding timings for each key number. . When a plurality of keys are pressed at the same time by the user, the arpeggiator uses a predetermined rule (for example, in order of increasing pitches) for note numbers assigned in advance to each of the keys simultaneously pressed. Etc.). Then, a note number assigned with a number corresponding to the key number in the stored arpeggio pattern is generated at a sounding timing corresponding to the key number, and the arpeggio is generated based on the key pressing sound. .
[0003]
Further, in the normal arpeggiator as described above, since the tone of the scale tone (for example, piano tone) is set on the sound source device side, the output of the arpeggiator is output as a distributed chord. By assigning a drum set tone color to (note) in a fixed manner, it becomes possible to output a predetermined drum sound in response to a key pressing operation of the corresponding key by the user. For example, for each of the notes “C3”, “E3”, “G5”, “A5”, “B5”, “C6”, each drum tone such as bass drum, snare drum, rotum, high tom, hi-hat close, hi-hat open, etc. And a drum sound corresponding to the note number corresponding to the predetermined note generated in response to the key pressing operation by the user can be generated based on the data. By doing so, the arpeggiator can also be used as a drum pattern generator (this is particularly called a fixed note type arpeggiator).
[0004]
[Problems to be solved by the invention]
By the way, in the conventionally known arpeggio generation device as described above, an arpeggio with an unnatural audibility may be generated depending on the number of performance operators operated simultaneously (for example, the number of key presses). there were. For example, in the case of an arpeggiator that generates an arpeggio based on an arpeggio pattern that is defined so that the sounding timing comes in order from the largest key number, if the user presses only one key, it is assigned to the key that was pressed The pitch may not be pronounced easily. In addition, there are arpeggiators in which the specified proxy sound is generated for the insufficient key numbers when the number of keys operated simultaneously is less than the number of key numbers defined in the arpeggio pattern. In some cases, a complex arpeggio is generated despite the fact that the number of key presses operated at the same time is small, so the smaller the number of key presses, the more the user wants a simple arpeggio to be generated. There are many inconvenient.
[0005]
The present invention has been made in view of the above points, and stores an arpeggio pattern in which a natural audibility is obtained according to the number of performance operators operated in advance, and the number of performance operators operated by a user.

[0017]
Here, arpeggio pattern data stored in the ROM 2, the RAM 3, or the external storage device 7 will be described. FIG. 2 is a conceptual diagram showing an embodiment of the data structure of arpeggio pattern data. 2A shows the overall structure of the arpeggio pattern data, and FIG. 2B shows an example of the pronunciation pattern data included in each type of arpeggio pattern data.
[0018]
Arpeggio pattern data is data that includes one or more pronunciation pattern data (details will be described later) that define the timing, tone length, volume, or octave shift of the pitch of each arpeggio component sound. Data prepared for multiple types, such as those set by. That is, as shown in FIG. 2A, arpeggio pattern data is stored for each type (for example, musical instrument type such as piano and drum), and the arpeggio pattern data for each type corresponds to the number of key presses. One to a plurality of pronunciation pattern data are included.
[0019]
As shown in FIG. 2 (b), the sound generation pattern data is one sound composed of five elements of timing (Timing), gate time (Gate), key number (Key), octave shift (Oct), and velocity (Vel). This is data in which minute data is stored for one bar. Timing (Timing) is data representing a clock value corresponding to the tone generation start timing of the musical sound, and gate time (Gate) is data representing a time length (clock value) from key-on to key-off of the musical sound to be generated. The length of the pronunciation pattern data is one measure (1920 clocks). In this embodiment, according to each timing value described, when the number of key presses is 1, quarter notes (first and third beats) When the gate time 480) is the number of key presses 2 to 4, the data constitutes an arpeggio pattern that generates quarter notes for each beat.
[0020]
The key number (Key) is data for determining the pitch of a musical sound when an arpeggio is pronounced. That is, a register corresponding to this key number is preset in the RAM 3, and the note number detected in accordance with the key pressing operation of each key in the arpeggio key range is stored in the register, so that the key number data according to a predetermined rule is stored. Assign a note number to. In the arpeggio generation process, the note number assigned to the key number in the pronunciation pattern data is read out from the register, and the note number is used as a note number that determines the pitch of the tone that produces the note number. Note that this note number does not always become the pitch of the musical sound itself because of processing such as octave shift. For example, when the number of key presses that can be detected according to the key press operation of each key in the arpeggio key range is set to 4, the key number is a numerical value of 1 to 4, and the value of this key number is the pitch change of the arpeggio Corresponding to the pattern, it is assigned in advance for each sound data.
[0021]
Octave shift (Oct) is data that specifies how many octaves to change when the pitch (note) specified by pressing each key in the arpeggio range is changed in octave units. It is. For example, in the case where the note number assigned to the key number is C3, and the octave shift value is designated as “0”, the pitch of C3 is kept as it is at the timing of generating the pitch of C3. When the octave shift value is stored as “+1”, the sound is generated with the pitch of C4 obtained by shifting C3 up by one octave at the timing of generating the pitch of C3. The velocity is data representing the velocity value (data used for volume control etc.) of the musical sound to be generated. Arpeggio pronunciation data corresponding to the number of key presses is generated in accordance with the tone generation pattern data defined for each key press number.
[0022]
In the electronic musical instrument shown in FIG. 1, the number of key presses when the user operates the keyboard is detected, and arpeggio sound generation data is generated by selectively using the sound generation pattern data corresponding to the detected key press number. Depending on the number of key presses, an arpeggio with a natural audibility can be generated. The arpeggio generation process for generating such an arpeggio is performed by the CPU 1 of the electronic musical instrument shown in FIG. 1 executing a predetermined program (software) that realizes the arpeggio generation process. The processing operation of this “arpegio generation process” will be described with reference to FIG. FIG. 3 is a flowchart showing an example of the “arpegio generation process”. This processing is executed when the device has been set to the arpeggio performance mode according to the operation of the arpeggio performance mode designation switch. Hereinafter, the processing operation of the processing will be described according to the flowchart shown in FIG.
[0023]
In step S1, the user selects an instrument type that he / she wants to arpeggio sound, and selects a type of arpeggio pattern data to be used for arpeggio generation from a plurality of arpeggio pattern data stored according to the specification of the instrument type. And read the corresponding type of arpeggio pattern data. In step S2, it is checked whether or not the key pressing operation of each key within the arpeggio key range is performed by the user. If the key pressing operation is performed by the user, the arpeggio pattern data already read in step S1 is included. Then, pronunciation pattern data corresponding to the detected number of key presses is extracted (step S3). For example, one of the pronunciation pattern data shown in FIG. 2B is extracted according to the number of key presses. In step S4, arpeggio pronunciation data is generated based on the pronunciation pattern data extracted in step S3.
[0024]
Here, arpeggio generation will be described using an example in which the detected number of key presses is three. Assuming that three keys assigned to note numbers “C3”, “E3”, and “G3” included in the arpeggio key range are pressed at the same time, the arpeggio pattern data for each type that has already been read is stored. The tone pattern data corresponding to the number of key presses 3 is selected from among them, and “C3” is selected for the key number “1 (Key = 1)”, “E3” is set for the key number “2 (Key = 2)”, and the key number. “G3” is assigned to “3 (Key = 3)” (however, the rule is that the note numbers of the keys pressed in the arpeggio key range are assigned sequentially from the note number on the bass side in order of younger keys) ).
[0025]
Referring to the sound generation pattern data with three key presses shown in FIG. 2 (b), both the first beat (Timing = 0000) and the fourth beat (Timing = 1440) have key numbers “1 (Key = 1) "is set, the pitch is determined by the note number" C3 "assigned to the key number" 1 ". At this time, since the octave shift of the first beat is “+1 (Oct = + 1)”, the pitch of the first beat becomes the pitch of “C4” one octave above “C3”. Since the octave shift is “+0 (Oct = + 0)”, the pitch of the fourth beat is directly the pitch of C3. Since the key number “3 (Key = 3)” is set for the second beat (Timing = 0480), the note number “G3” assigned to this key number “3” causes the pitch to increase. Since the octave shift of the second beat is “+0 (Oct = + 0)”, the pitch of the second beat becomes the pitch of “G3” as it is. Similarly, since the key number for the third beat is set to “2 (Key = 2)” and the octave shift is set to “+0 (Oct = + 0)”, the pitch of the third beat is “E3”. Becomes the pitch. In this way, when three keys assigned with note numbers “C3”, “E3”, and “G3” included in the arpeggio key range are simultaneously pressed, the first beat is “C4”. An arpeggio for one measure composed of quarter notes (Gate = 480) with a pitch of “G3” for the second beat, “E3” for the third beat, and “C3” for the fourth beat is generated. It will be.
[0026]
As described above, the note number of the key pressed in the arpeggio key range is referred to by the key number, and the note is played as it is at the pitch of the note number according to the sound pattern data corresponding to the number of keys pressed, or the octave shift Or pronounce it with the pitch you played. That is, the note number of the pressed key is pitch information that determines the pitch of the arpeggio constituent sound.
[0027]
Next, arpeggio generation when the arpeggio pattern data is defined by a fixed note, that is, when a fixed note type arpeggiator is used will be described with reference to FIG. FIG. 4A is a conceptual diagram showing an example of an arpeggio output pattern generated using a fixed note type arpeggiator. Here, the horizontal axis is time, and the output pattern is indicated by a circle. FIG. 4B and FIG. 4C are conceptual diagrams respectively showing examples of pronunciation pattern data used in the fixed note type arpeggiator. In this embodiment, a drum set tone for a predetermined note, for example, notes “C3”, “E3”, “B5”, and “C6”, respectively, bass drum, snare drum, hi-hat close, hi-hat, respectively. A case where each open drum sound is assigned will be described as an example.
[0028]
The configuration for realizing the arpeggio output pattern as shown in FIG. 4A by using the fixed note type arpeggiator has the following two configurations. First, as the first configuration, a plurality of pronunciation pattern data corresponding to the number of key presses for each type is prepared in advance as the above-described configuration, that is, arpeggio pattern data, and it corresponds to the number of key presses at the time of arpeggio generation. The arpeggio is generated by using the pronunciation pattern data. As shown in FIG. 4B, in this case, the sound pattern data is defined so as to correspond to the number of key presses, and each sound pattern data includes timing (Timing), gate time (Gate), note number. (Note), data of one sound consisting of four elements of velocity (Vel) is stored for one measure. The timing, gate time, and velocity are the same as those shown in FIG.
[0029]
The note number is pitch information corresponding to each drum tone. In the embodiment shown in FIG. 4B, only the note number “C3” is generated in the sound generation pattern data corresponding to the number of key presses 1, and the note number “C3” in the sound generation pattern data corresponding to the number of key presses 2. “C3 + E3”, note numbers “C3”, “B5”, and “C3 + E3” in the pronunciation pattern data corresponding to the key depression number 3, and note numbers “B5” and “C3 + C6” in the pronunciation pattern data corresponding to the key depression number 4. ”And“ C3 + E3 + C6 ”are defined together with the sound generation timing, sound length, volume, etc. of each arpeggio component sound. That is, the sound pattern data corresponding to the number of key presses 1 is “bass drum” pattern only, and the sound pattern data corresponding to the key press number 2 is “bass drum” pattern in addition to the “bass drum and snare drum” pattern, The sound pattern data corresponding to the number of key presses 3 is the “bass drum” pattern, the “hi-hat open” pattern and the “merge bass drum and snare drum” pattern, and the sound pattern data corresponding to the key press number 4 is the “hi-hat open” pattern And “Mass of bass drum and hi-hat close” pattern, “Merge of bass drum and snare drum and hi-hat close” pattern (see FIG. 4A), etc. Stored in the sound pattern data, and the sound pattern data is cut according to the number of keys pressed. Instead to use.
[0030]
In this way, the sound pattern data corresponding to the number of key presses is prepared, and the configuration using the sound pattern data corresponding to the number of key presses by the user at the time of arpeggio generation is based on the fixed note type arpeggiator. In this way, in the fixed note type arpeggiator, the timbre increases as the number of key presses increases, and the sound has a natural and varied sensation. Arpeggio can be generated.
[0031]
As a second configuration, a plurality of tone pattern data corresponding to each drum tone color are prepared as arpeggio pattern data regardless of the number of key presses for each type, and these tone generation patterns are generated according to the key press number at the time of arpeggio generation. In this configuration, an arpeggio is generated by using a combination of one or more data. For example, as shown in FIG. 4C, as the sound generation pattern data, bass drum (note number “C3”), snare drum (note number “E3”), hi-hat open (note number “B5”), hi-hat close ( Four tone generation pattern data each defining a note number “C6”) are defined. If the number of key presses is 1, for example, only the “bass drum” pattern is generated using only the pronunciation pattern data in which the note number “C3” is defined. When the number of key presses is 2, for example, the “bass drum” and “snare drum” patterns are generated by combining the sound generation pattern data in which the note number “C3” and the note number “E3” are defined. When the number of key presses is 3, for example, a combination of pronunciation pattern data in which a note number “C3”, a note number “E3”, and a note number “B5” are defined is combined with a “bass drum”, “snare drum”, Generate a “hi-hat open” pattern. When the number of key presses is 4, for example, a combination of pronunciation pattern data in which a note number “C3”, a note number “E3”, a note number “B5”, and a note number “C6” are defined is combined with a “bass drum”. , “Snare drum”, “hi-hat open”, and “hi-hat close” patterns are generated.
[0032]
In this way, even if the pronunciation pattern data used in accordance with the number of key presses is used in combination, in the fixed note type arpeggiator, the tone can be increased as the number of key presses increases. You will be able to produce arpeggios with natural and varied audibility. Note that the combination of the pronunciation pattern data to be used according to the number of key presses may be preset in advance or set appropriately by the user.
[0033]
In the above-described embodiment, four keys are shown as the number of key presses, but the present invention is not limited to this. Also, when the number of key presses is larger than planned (for example, 5 or 6 sounds in the case of 4 sounds planned), the one with the largest number of key presses is used among the prepared pronunciation pattern data. You can do it.
Note that the sound generation pattern data used for the fixed note type arpeggiator may define information specifying sound effects instead of note numbers. Also, note numbers and information for designating sound effects may be defined together, and information used for arpeggio generation may be switched and used based on the magnitude of velocity at the time of key depression. For example, a note number may be used when it is below a predetermined velocity value, and information specifying a sound effect may be used when it is greater than a predetermined velocity value.
[0034]
Note that the pronunciation pattern data format is “Event + Relative time” that represents the time of occurrence of each event as the time from the previous event, and “Event” that represents the time of occurrence of the event as an absolute time within the song or measure. “Absolute time”, “pitch (rest) + note length” expressed in note pitches and note lengths or rest and rest lengths, a memory area is secured for each minimum performance resolution, and an event occurs Any format may be used such as a “solid method” in which an event is stored in a memory area corresponding to a time to be performed.
[0035]
【The invention's effect】
According to the present invention, an arpeggio pattern that allows a natural audibility to be obtained according to the number of performance operators operated in advance is stored, the number of performance operators operated by the user is detected, and the corresponding performance operator is stored. Since the arpeggio is generated by selectively using the arpeggio pattern according to the number, the user can easily generate an arpeggio with a natural sensation according to the number of performance controls operated. The effect is obtained.
